The NHL department of player safety's Patrick Burke, in a video, said that Weise was eligible to be hit at the time, which wasn't the case with Stepan, whose jaw was broken on the play.

"The time between the release of the puck and the moment of contact (with Weise) is within established NHL standards," Burke said.

The difference is Moore's shoulder struck Weise's head, evidenced by his helmet flying off. Even though there was incidental contact with Weise's shoulder first, Burke said Weise's head absorbed the brunt of the impact.

"The onus is entirely on Moore to make sure he makes a full-body check that does not make Weise's head the main point of contact," he said.

Weise, who was groggy after standing up, returned to Tuesday's game.

"He went to the quiet room and saw a doctor and they felt he was good to go," Canadiens coach Michel Therrien told reporters after the game.

Therrien had no update on Weise on Wednesday, but the league said he suffered an injury on the play.

Moore and Weise had checked the other twice each in the game before the one that drew the league's attention.

Rangers coach Alain Vigneaut said after the game that the hit was late, but changed his tune on that on Wednesday.

"The player didn't see him coming, obviously, but the guy was admiring his pass a little bit at the same time," he said of Weise. "Unfortunately, it was a hit and because of the force of the hit, the head seemed to snap back a little bit.

"But as far as what I know about league standards and from what I heard from the Prust hit where the dynamics of the hit changed because Stepan was hurt, I don't see that at this time right now."

Prust will return from his suspension in Game 6 in New York on Thursday, just as Moore begins serving his.
